An example elevator system may include a shaft in which at least one elevator car can be vertically displaced. The elevator car may be coupled to a counterweight via a cable arrangement wherein the cable arrangement has at least one cable portion. Horizontal deflection of the cable portion can be limited by at least one limiting member. In some examples, the at least one limiting member may be configured as a limiting roller that is mounted laterally alongside the cable portion such that it can be rotated about an axis of rotation and can be made to rotate by a controllable rotary drive that depends on a speed and a movement direction of the cable portion.

Elevator installation

An example elevator system may include a shaft in which a first elevator car and a second elevator car positioned below the first elevator car are separately movable up and down in a vertical direction along a common guideway. The first elevator car may be coupled to a first counterweight by first suspension ropes and by first compensation ropes, and the second elevator car may be coupled to a second counterweight by second suspension ropes and second compensation ropes. Further, first and second ends of the first compensation ropes may be secured to the first counterweight or to the first elevator car. The first compensation ropes may be guided around at least one roller positioned on a bottom surface of the first elevator car or on the counterweight.

An elevator installation includes a shaft in which a first elevator car and a second elevator car arranged below the first elevator car are movable upward and downward in the vertical direction separately from each other. Each elevator car is coupled to a counterweight via a rope or belt arrangement. At least one rope or belt arrangement has two rope or belt sections via which one of the elevator cars is coupled to a counterweight and which extend laterally along the other elevator car. In order to avoid impairment of an elevator car by rope or belt oscillations, the elevator car has at least one limiting member which is held in a predetermined position in the shaft and is assigned to a rope or belt section and has at least one limiting element which is movable between a limiting position and a release position depending on the position of the elevator car which is coupled to the counterweight via the associated rope or belt section. In the limiting position, the limiting element can be positioned on that side of the rope or belt section which faces the elevator car, and, in the release position, the limiting element releases said side.

An elevator installation includes a shaft in which at least two elevator cars are arranged one above the other and are capable of travel upward and downward in a vertical direction separately from one another, wherein each elevator car is assigned a travel drive. The elevator cars are capable of travel with large and small spacings to one another without the risk of collision by coupling at least two elevator cars together by way of a variable-length, releasable coupling device, wherein the spacing between the coupled-together elevator cars can be varied, in a manner dependent on the relative speed between the two elevator cars, with the aid of at least one of the travel drives.
